Fusion is when a force causes the nuclei of two atoms to merge together. Say, for instance, two hydrogen atoms (each containing a single proton in their nucleus) are near each other. Normally, they give great resistance to being put too close. However, a force (most likely incredible heat) manages to force their nuclei together. They become a single nucleus, containing two protons. It now has the structure of helium, and is considered to be it.
Small nuclei combine to form larger nuclei
A new idea that could be a answer to energy problems.
Nuclear fusion is the phenomenon of binding two different atoms to produce a new atom, with a big release of energy.
Both Chemical and nuclear reactions form new substances.
Nuclear fusion
Chemical reactions, normally. However, radioactivity, nuclear fission, or nuclear fusion also fit this definition.

Nuclear and Chemical changes result in new substances.
Chemical synthesis form a new molecule; nuclear fusion form a new atom.

The process of combining elements to create a new element is nuclear fusion. As we normally consider it, in this process, a great deal of energy is liberated. They are exothermic. But there are types of fusion that are endothermic, though we only encounter them in something like a supernova.
Nuclear fusion. Stellar fusion involves a ton of different fusion reactions throughout the star's life. The primary and (usually) the longest burning is the fusion of hydrogen into helium. This consumes a great number of the nuclear energy in the sun, and it usually accounts for the type of fusion that goes on for most of the life of the star. This is the process.
Small nuclei combine to form larger nuclei
They are...reactions and can lead to new elements; but the big difference is that a nuclear fusion involve particles from the atomic nucleus and a very great energy is needed.

That is nuclear fission. An example is that of a Uranium-239 atom undergoing beta decay. That is, a neutron in the nucleus ejects and electron, becoming a proton, resulting in Uranium-239 becoming Neptunium-239.
Nuclear fusion has been used for nuclear transformation, which is the production of new materials by fusion, and for the type of specific type of transformation called nuclear synthesis, which is the production of materials not normally found in nature. It has been used in nuclear bombs, specifically fusion bombs or hydrogen bombs. There is hope that nuclear fusion can be used to provide power for generation of electricity, though this has not yet been achieved in a practical system.
